With Election Day drawing nearer, the National Republican Congressional Committee is pulling advertising dollars from two seats—one where the GOP incumbent is favored to win and another where Republicans fear their candidate could lose. 

The NRCC is cancelling its spending in the San Antonio Media market from Oct. 16 through Election Day, as Republicans feel optimistic about Republican Rep. Will Hurd's position against his Democratic opponent, Gina Ortiz Jones. 

There's been little public polling in the district, as in most congressional races. But the New York Times/Sienna College poll last month found Hurd up by 8 points, and Hurd had significantly outfundraised Ortiz Jones through June in a cycle where other Republican incumbents have lagged behind. 

But there's a more ominous sign for Republicans in Arizona's 2nd Congressional District, which is being vacated by Republican Rep. Martha McSally's Senate bid. 

The NRCC is cancelling upcoming television buys in that race, a Republican familiar with the strategy confirmed, where former Democratic Rep. Ann Kirkpatrick is facing off against Republican Lea Marquez Peterson. 

The same dearth of public polling exists in this race, but the NYT/Sienna poll put Kirkpatrick up 11 points. And Kirkpatrick came into the race with stronger name identification from her previous stint in office (albeit in a neighboring congressional district). Even though Republicans have touted Marquez Peterson's strength as a candidate this cycle, she may not be able to hold the seat that voted for Democrat Hillary Clinton in 2016. 

These are the kinds of painful decisions that both parties will have to make in the closing days, as Republicans look to defend the right incumbents to keep a hold on the House majority and Democrats try to win the right combination of seats to take control of the House.
